The key to smart investing is not reacting to the headlines of what's already happened but looking six months ahead and predicting what's going to happen, Jim Cramer told the viewers of his "Mad Money" TV show Friday.

Cramer reminded viewers that the stock market always looks into the future. He said it's easy to say things will get worse when they're already bad, but it's far harder to predict a recovery when the markets are at their lows.

Cramer then offered his predictions for the second half of 2009. First off, he said the turn in the housing market is upon us, and that means fewer foreclosures and more profits for banks like

Wells Fargo

(WFC) - Get Report

, a stock which Cramer owns for his charitable trust,

Action Alerts PLUS. He also recommended Washington, DC area homebuilder,

NVR

(NVR) - Get Report

as a housing beneficiary.

Cramer said the trucking industry is also at record lows, and he feels companies like

Paccar

(PCAR) - Get Report

should benefit in the second half.

He also reiterated the multi-year move in the smartphone market, saying that

Apple

(AAPL) - Get Report

and the smartphone component makers will also prosper.

Finally, Cramer predicted windfalls for the healthcare and natural gas sectors, as they too will recover during the second half of this year.

He said that investors need to take a chance and make predictions if they expect to get ahead, and that's why he's always looking toward the future.

Prescription for Profits

Cramer spoke with

Allscripts-Misys Healthcare

(MDRX) - Get Report

CEO Glen Tullman to see if this company still has the prescription for profits after a 200% run since Cramer last recommended the stock in July of 2008.

"We're just getting started," said Tullman when asked about Allscripts' business outlook. He said that with only one out of three doctors using the company's software, Allscripts has a ton of opportunity ahead of it. Tullman said the company just recently grew its distribution network five times and is reaping the rewards of trends towards healthcare reform.

When asked about the company's exposure to the cash-strapped hospital sector, Tullman said that fortunately 80% of all healthcare is provided outside of hospitals, so Allscripts is not significantly affected. He said that in many cases hospitals are postponing larger projects due to financial concerns, but they're still moving forward with investments in technology like Allscripts offers.

Cramer said he's not backing away from Allscripts and reiterated his buy on the stock.

Speculation Friday

For "Speculation Friday," Cramer recommended oil and gas driller

Continental Resources

(CLR) - Get Report

, which has been left for dead by Wall Street.

Cramer last recommended Continental on May 9, 2008 it was at $53. The stock them peaked at $83 a share before falling with the markets to a low of $12. Since then, shares have recovered to $27 a share, and Cramer said the time is right to pull the trigger.

According to Cramer, Continental is a much better company now than it was a year ago, yet it trades at half the price. Continental now drills wells 50% faster than it did last year, in just 30 days on average versus 45 days in 2008. The company is also better run, and none of its $500 million in debt is coming due anytime soon.

Cramer said Continental is also very well run, with management reducing the company's rig count from 32 rigs to just four at the lows. Two-thirds of the company's production is oil, not gas, and 100% of that production is unhedged, meaning it can profit from rising crude prices.

Cramer said Continental could be a potential takeover target given its substantial reserves. With two ways to win, he said investors need to consider this stock.

Missed Opportunity

In his "Outrage of the Day," Cramer sounded off at the entire natural gas industry for completely missing out on the country's push towards alternative energy. He said despite natural gas being the logical choice as a bridge fuel for the country, both Congress and Obama have shunned the clean burning fuel.

Cramer said he's not sure who to blame for the Obama administration endorsing practically every other fuel other than natural gas, but it's clear that true alternative energy is 30 to 40 years away, and that natural gas, which is cheap, plentiful and clean is the bridge fuel the country needs.

Cramer said he's just shocked that natural gas industry has seemingly blown its chance for prosperity.
